Tony whenever you post or reply ( except for the default Quick Reply ) there is a link to the forum File Manager. You click on that, click on Browse to the file on your PC then click on Add File and just wait for it to upload .. then click Done. Once you have done it once it will be easy the next time. Then when you submit your post it will appear as an attachment.

Nigel, Thank You,... That is what I have done, but I often get the message that the file is too large even though I know that it is not... Can you tell me what the problem might be with that... Thank you
